Didn't manage to watch the USO final, but it didn't take Sinner long to see off Fritz.

Djoko v Hijakata would be interesting if it was on a bit later.  He's also playing doubles with Nick Kyrgios and won their first match.  Can't be bothered with Raducanu anyway.  Also thought Andy was coaching Djoko, or is that only for the AO?

Emma Raducanu has withdrawn from this week's WTA event in Auckland because of a back problem.

The 22-year-old was due to play Robin Montgomery of the United States in the first round of the ASB Classic on Tuesday.

Raducanu will now fly to Melbourne to continue her preparations for the Australian Open, which begins on 12 January.

"Tried my best to be ready," she said. "I love Auckland and the fans here, but unfortunately I picked up a back niggle and won't be ready in time.

Time she thought about retiring because she's not going to achieve anything at this rate unless her recently acquired Japanese fitness trainer can sort her out.
